CARTON-FEEDING DEVICE.

Application fil ed October 16, 1922, Serial No. 594,796. Renewed July29, 1926.

10 pared and sh pped fiat involves certain inherent diiiiculties ingetting it from its flat or folded state into its erected or opened upposition by mechanical means.

This difiiculty is primarily due to the natural set given to thecartonwhile in its fiat state with the folds at d' onally oppositecorners, creased hard they naturally become when closely packed togetherand the opposite corners flattened out. T his set in the folded cartonnaturally malres it tend to sta-v closed and to return to a closed orpartly collapsed condition after it is opened up.

i It is obviously of great importance that the carton when set up be astruly rectangular possible. The problem of handling has been variouslytreated in the art and a variety of opening up mechanisms have beendevised. V

0 My present invention includes in part certain novel instrumentalitiesand combinations by which a maximum of accuracy and speed is obtainedw.t-h a minimum of waste due to tearing), and crumpling of the papercartons.

This with various improvements in the feeding of the cartons to theopening up point and their subsequent delivery for sue (cedingoperations according to my present invention may best be understood byreference to a practical embodiment and I have therefore shown in theaccompanying drawand will describe in the following specification a ma....ine whivl'i have tested out and which in accordance with myinvention and well illustrative thereof.

Fig. 11 is a fragmentary plan view of the cross slide in itstransferring movement, and

Fig. 12 is a detail of the carton follower.

In the embodiment of my machine which I have shown in these drawings asillustrative of my invention, mount on a base 1 a slide frame or head 10on which and on the base 1 are mounted slides and 30.

The base 1 is formed with an overhang 1 as will be seen in Fig. 3, whichsupports the head 2 transversely of a conveyorfram'e 40 along which theknock down or flat cartons are advanced to the transfer slide 20. Theconveyor 41 is of the chain feed type running on sprockets 42 to advancethe vertically disposed pack of cartons longitudinally-of the frame 40and between the rails sup: ported on uprights 44 at each side of theway. The rails 43 are disposed two on one side of the conveyor 41 andone on the opposite side, the odd rail being; disposed about midway theheightof the two opposite rails so as to give a three point support forthe. stack of cartons as they move past.

The sprocket 42 is advanced by a ratchet drive comprising a ratchetmounted fast on a shaft 51 and turned by a pawl 52 car- .53 and Manglesthereto. The rod 62 has a forked end ried by an arm 53 looselymounted on shaft 51. This pawl is reset by an eccentric 60 on a shaft61* througih a rod 62 which is connected to an arm 54. integral with thearm disposed at substantiallv right which embraces the eccentric 60 andis engaged thereby whenever the rod (32' lowers it. The arm 54 is alsoconnected with a spring 55 fastened at 56 to the base of the machine andtending),' to rockthe pawl arr 53 and thus turn the sprockets 4-2 toadvanvie the carrier 41. This spring 55 constitutes predetermined motivepower to the conveyor drive.

The return motion of the ratchet is effected by the eccentric 60 whichresets the paw-loathe main power shaft 61 whenever the transfer slidehas reduced the number if cartons sufliciently to allow thespring todraw down the arm 54 so that the eccentric 60'finds bearing at itsbottom. thus resets the ratchet to advance the carrier under the actionof the spring whenever the reduction of pressure adjacent the transverseslide permits the action of the spring 55. i

The spring 55 therefore keeps the pressure within predetermined limitson the blanks in advance of the follower as. This follower 4-5 consistsof a heavy block hai pins M3 in its lower face which engage with each ofthe conveyor chains 4-1. As the cartons are'placed on the conveyor theblock 4e5zis placed behind them a follower to hold the cartons erect andto insure their advance and their free presentation to the transfer.slide 20.

Referring to Fig. 7 whica is a plan view of the transfer slide head withthe brackets 1-1 removed, the slide 20 is gibbed into a way 21 theentire width of the frame. It is reciprocated along this way bv a leverhaving a forked end71 which receives between its jaws a block 72 whichis loosely pivoted. on a stud 3 carried by the slide 20. V The lever 70is pivoted at i l to the bracket on. the base. 1. It carries at itslower enda roller 75 whichv runs in .a cam. slot 76 on a cam 77 which isfast on the power shaft 61. Mounted on astud is a bracket 80 carrying anadjustable stud 81 which is disposed to strike a. jogger lever 82pivoted at 83 and normally held up towards the bracket by aspring St.This spring; 84- is fastened at 85 to a bracket and at 86 to a hookwhich projects out from The receiver casting 90 is pivotally mounted at93 to bracket 9-1 which 1s mounted on the slide head 10. it is held inposition by a loose bolt 95 which can be released readilyin case of ajam in the carton receiver. in such an event the casting" fill may beswung on its pivot 93 and the iti'nmed cartons removed without troubleor delay.

To the rear of the diagonal line between the corners 91 and 92 thereceiver hollowed out as at 96 so that the carton as m d eated at (l isfree to expand rearwardly as well as forwardly. This is important as thenature of the opening blade ltltl expands the rarton slightly whilestill in its initial position asiu Fig". 8 and it is important and lhave discovered that it is important to permit the carton to expandsymmetrically in both directions in order to avoid distortion andpossible tearing.

The lower side of the carton receiving pocket is closed by a plate 110which is slotted at 111 for the position of the blade 100. In its upwardposition the blade Hill is guided by a. similar plate 110 which proiectsabove the pocket men'iber 90. The blade 100 is carried in a slide 101mounted in a slideway 102 adjust-ably held to the. slide 101 by bolts1th.. The slide 101 is vertically reciproci ted by a link ltlil vownectcd to one arm ll tl: with a bell crank pivoted at 105 and having itsopposite end provided with a roller 106 ninnir in the cam groove 10'? ofthe cam 108.

This cam is fixed on the main shall G1. The shatt 61 1s driven by asproeke (32 a t one end and at its opposite end has a hand wheel 3 bywhich the machine. may be turned over by hand when so desired.

The slide 30 carrying the vertically tociprocating blade 100 is itselfreciprocated at right angles to the transfer slide 2) by a lever 31. Thelever 3i is slotted as at 132 to receive a block held by a stud 3.4 tothe slide 30 so to vary the throw of the lever with the motion of theslide. The lever is pivoted at its lower end as at 36 and is rocked by aroller stud 8T runningin a. cam groove in the cam 38 also fast on thepower shaft 61.

It will therefore be seen that in this grou p of parts last. described,the bladelOO can be raised past the plane of the plate 110, projectingthrough the slot .111 so as topenelid wtrate the fiat carton Csubstantiallyin the line of that one of its flattened out corners whichlies facing forward or in the direction in whichit is advanced.

\Vhen the blade 100 enters the carton C at this point it begins toexpand it. The carton being held by its edges as above described is freeto expand in both directions of its opening movement so that when theblade 100 has passed through it, it is symmetrically opened up withtheblade against the inside of whatis to become one of its corners, butwhich up to this time has been pressed flat.

The slide now moves forward advancing as the blade 100 which moves thecarton out of the opposite corner 91, 92. between which it has beenheld. (See Figs. 8 and 8); As appears in the latter figure it will benotedthat the carton C has been brought in contact .with a pair ofguides These guides converge at first but later become parallel so thatthe inner corner of the carton meets a slight resist ance or drag whichtends to swing the ad jacent panel about the edge of the knife as apivot to a position at right angles to that which it occupied when flat.As the blade moves forward this panel traveling against the parallelface of. the guide 120 meets no resistance while the forward edge of theopposite panel being still in engagement with the guide face 121 isretarded. In this position as shown in Fig. 8 the carton is opened outpast its normal rectangular posi-' tion so that the folds orcorner-scorings -which have been flat prior to opening are given a foldor set in excess of that which is desired. The corners, which have beensharply folded when the carton was flat,

are opened out at a more obtuse angle than their ultimate position so asto counteract the tendency of the carton to return to the flat conditionin which it wasoriginally.

At the end of the movement of the slide 30 along its slideway 39, theblade 100 reaches the inner corner of the carton pocket 140. For thepurposes of the present disclosure this pocket need only be consideredas one of a plurality of successively presented pockets each adapted totake an openedcarton in turn. They are in fact, in the embodiment shownthe receiving pockets of an end flap closing mechanism with which thisembodiment is especially adapted to operate.

Fiach pocket 140 has one of its lateral walls 14-1 pivoted. at 142 whichis opened by a roller M3 which is moved vertically as indicated by thearrow in Fig. 10 to a position in. which it contacts with a tail 144 onthe pocket wall. This wall is opened as the blade 100 approaches withthe carton trail- 'ing thereon.

When the blade reaches the corner as shown in Fig 8 the trailing panelclears the end of the guide 121 and under its own natural tendency thisside snaps forward into the pocket. The seating of'the carton G in thepocket is assured by the spring pressed return of the wall latl whichsnaps nst the edge panel and about its corner. The wall 141 has anoverhang lip 1 which closes about the outer edge, thus holding thecarton in position and at the same time giving it a slight diagonalpressure in the direction of the blade, thus completely as suring thecompleteness of the angular coincidence between the carton and thecorners of the pocket.

At this point the blade 100 retreats. being lowered along this slideway102 under the action of a cam 107 through its bell crank and linkconnection. As soon as the blade has cleared the plate 110, the slide 30is returned by .its cam 38 to its original carton penetrating positionbeneath the pocket 90. in the meantime the transfer slide 20 has 'vancedanother carton to be opened and no. 'tioned it with its edges in thecorners 9i; and 92.

The details of the pocket90 and the carton engaging edge of the slide 20are shown in the enlarged fragmentary view of Fig. 7. In this view itwill be seen that the edge receiving portions 91, 92, referred to generally as the corners are defined by one wall of the guide 120 and apair of catches 122 which are just behind the carton when it isdelivered into the pocket 90 by the action of the springs 122 whichpermits that the pawls yield upon the advance of the carton which pushesthem out of its. path as it is moved forward with the slide. The edge ofthe slide 20 is providedwith a lip 20 carefully formed to the exactthickness of the folded carton'edge so that it will pick the carton fromthe end of the pack in the carrier and advance it along the slidevwavto. the carton receiving knife.

In order to have the transfer slide 20 accurately and evenly engage theedge of the most advanced carton in the pack and remove it thereformwithout danger of crumpling or tearing it, it is necessary that theblanks be presented with a uniform pressure as maintained by the ratchetconnection and the spring which keeps the conveyor block or follower 15up against the carton pack. The tension on the spring 55 is restored atfrequent intervals by the eccentric which constitutes a continuouslyacting urge although, through the pawl and ratchet connection. theconveyor is only driven intermittently.

It is also important that the cartons be presented in the properposition and that the pack adjacent the transfer slide be squared up andeven. This is partly accomplished by the disposition of the rails 43. Asabove described, there are two of the III at: 154 is pivoted a rockerrod 1-541.

rails on'one side and the third on theopposite side thus affording athree point line of contacts; The. action or the jogger 82 restores thealignments of any cartons that may possibly be irregularly positioned inthe pack. At each stroke oi the cross slide the tail of the leverstrikes the side of the carton pack just atter the carton has beenremoved from it, thus assuring not only the alignment of the cartons butthei freedom to 'move up promptly behind the conveyor slide under thepressure of the conveyor driving spring 55.

Extending across the head of the machine "and jourualledin brackets 11is a shatt 150 Adjacent lever 'lol and also fast to shaft 150 is a shortarm 153 on the end of which This rod is pivoted at its lower end to arocker The rock r 155' is pivotally mounted at 155% and carries a block156 to which is pivoted at"1"57 a slide 15; to operate in the slideway'158 of the guide 43 Suitably mounted within the slide 157 andshouldered'to receive-a compression spring 159 is a carton urger 157?operated by the upwardth'rust ot-the lever 1524 to oscillate the rocker155 around pivot 15532.11 disposed to advance the slide 157, by whichmeans the cartons ahead of the carton urger are also advanced by contactof carton urger to facilitate their 'delivery to the slide as shown inFigs. 10 and 11.

hen the conveyor l]. is advanced by operation of the ratchet drive toadvance pack towards slide 20, the cartons contacting with the-back sideof the carton urger 157 slide alongthe' angular surface 157 of thecarton urger compressing the spring 159., as shown in Fig. 7, and travelthe predetermined distance, after which the carton urger returns to anoperative position by the ex pension of the spring 159.

\Vh'ile I have referred to the machine herein shown in some detail as tomechanisms; it will be understood that many of the .mechanisms niay bevaried and modified or other equivalent mechanisms substituted. All suchmodificat ons are to be understood as within the scope of my presentinvention, and while {I have referred to my machine particularly for thehandling of cartons, many ot'its novel features may be utilized infeeding other flat blanks or pieces of stock for subsequent operations.
